MACHINE FOR CUTTING BEET-ROOTS.

SPECIFICATION forming part of Letters Patent No. 614,446, dated November 22, 1898.

Application filed January 24, 1898. Serial No- 667,744. (No model.)

To aZZ whom it may COHOGWZ:

Beit known that I, HAROLD P. DYER, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio,have invented certain new and useful Improvementsin Machines for Cutting Beet- Roots,of which the following is a specification.

My invention relates to improvements in machines for cutting beet-roots into slices adapted to the extraction therefrom of the saccharine juice by diffusion in which the cutter-knives are secured to a horizontal disk which is rotated at the bottom of a receptacle containing the beets. It is obvious that the machine is also adapted for cutting up various kinds of vegetables, to.

The objects of my improvements are, first, to reduce the friction of the moving parts of the machine; second, to afford facilities for the proper adjustment of the knives, and, third, to provide a machine the parts of which are easily accessible and which is convenient to operate. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical section of the entire machine. Fig. 2 is a plan view of a portion of the cutting-disk. Fig. 3 is a vertical section through the knife-box on line as 00 of Fig. 2. Fig. 4 is a plan view of the upper end of the shaft E. Fig. 5 is a vertical section through the upper bearingof the shaft E. Fig. 6 is a plan view of the preferred form of ball-plate, which is also shown in section at e, Fig. 5.

The bed-plate A, resting on suitable beams and provided with bearings B and B for the driving-shaft O and supports D D for the thrustbearing of the vertical shaft E, con- Securely attached to the lower end of the Ver-- tical shaft E is the cutter-disk F, which carries the knives G, and is rotated by means of a bevel gear-wheel H on the driving-shaft, engaging With the bevel gear-wheel I, which is fastened to the disk, thus applying the power mental ring-shaped aperture J to receive a hopper K, into which the beets are fed, thus permitting the beets to rest upon the cutterdisk E, which revolves in close proximity to the under side of the bed-plate. The cutter disk F is provided with a number of approximately rectangular openings fitted to receive the knife boxes or frames L, which rest on the stops a a, fixed to the disk. The cutterknife G, Fig. 3, is preferably bolted to an adjustable block M, which is clamped firmly to the knife-box L by the bolts N. In front of the bolts N and screw-threaded inthe knifeboX L are adjusting -'screws 0, which bear against the bottom of the block M, by means of which the cutter-knife may be raised or lowered, thereby cutting slices of any desired thickness from the beets. The counterpiece P is bolted firmly to the knife-box, having its upper face level with the surface of the disk. It has been the practice to adjust the counterpiece, which when its upper face was above the level of the disk caused much undesirable friction by rubbing against the beets. By adjusting the knife instead of the counterpiece I have overcome that unneces sary friction.

The vertical shaft E, carrying the cutterdisk, is journaled in the bed-plate at Q and also at R and is provided at its upper end with a collar S, integral therewith. Near the periphery of the collar S and screw-threaded therein are adj usting-screws b, which bear against the collar c, which collar is supported and revolves on rows of hardened steel balls d, forming an adjustable antifriction-bearing supporting the shaft E and cutter-disk F.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. The combination, with a horizontal revolving disk carrying cutter-knives and secured to a vertical shaft having a collar at its upper end with suitable adjusting-screws therein, of an antifriction ball-bearing supporting said shaft and disk, substantially as described.

2. The combination,with a horizontal disk, secured to a vertical shaft, and carrying outter-knives near its periphery, and a bevel gear-ring on its upper face between the knives and the lower bearing of the shaft having teeth adapted to engage and be driven by a bevel gear-wheelon a driving-shaft C, of an antifriction-bearing composed of rolling balls and suitable plates and adjusting-screws for the same interposed between a collar on the disk-shaft and the upper bearing thereof by means of which the cutter-disk is upheld, substantially as set forth.

In testimony whereof I affix my signature, in the presence of two witnesses, at Cleve- 10 land, Ohio, January 19, 1898.

HAROLD P. DYER.
